IMPROVEMENT iN MACHINES FOR CLEANlNG WHEAT.

Spcciliealiou forming part of Letters Patent No. 25,!39, dated August l0, 1358.

yand Double-Acting CentrifugalVheat-Rubber#7 and'we do hereby declare that the following is a full and exact. description of the same as nearly as practicable to be described.

This invention differsfrom all other smut- `machines orwheatvcleansers in many instances,

and is calculated to clean or cleanse wheat of i all articles of lth, or substances which should not be ground with the wheat for bread, and at the same time to save the defective grainsA of wheat and cheat in a clean state for horsefood, by separating this article from the dust and cockle by a process differing from all other inventions designed for this purpose, and is correctly demonstrated by the diagrams and1 drawings as referred to in the following explanation. The wheatis first passed through a small screen constructed with two riddles, as represented on' Figure 3. and marked H, the upper riddle, (marked M,) being so calculated as to let the wheat pass through with ease, while all articles of greater dimensions than wheat-grains are passed off at the spout L, the wheat and all smaller articles falling' through upon the lower riddle, (marked N,) this riddle being so constructed as to let all articles through smaller than grains of wheat-such as cockle and small gravel-which fall upon the incline i'loor or plane, (marked a) and by the shaking of the screen by the eccentric or cam, (marked It) striking against the stay, (marked S,) and thrown back by the spring, as seen at U, coming against the stay (marked i) in quick motion, the cockle and small gravel are thrown' off at the spout T. The wheat, so riddled of much filth, then passes into the hopper G, (best seen at Fig. l, which exhibits the front view of this invention.) This operation is performed by aband around two pulleysone on the main shaft of the machine, as seen at g, Fig. 3, the other on the axes of the cam, as seen at f, Fig. 3, end view of the invention. After this iirst process, the wheat being so riddled, it falls intothe hopper G and enters the arch F through an opening about six inches above the end of the arch F and immediately over I the hopper, (marked Y.) as seen in Fig. l. The

wheat on entering this opening in this archis again filtered by an atmosphericprocess called suction, which is created by the power of the fan drawing the atmosphere through the arch F, immediately over the hopper V. At this point the wheat falls into the hopper V and enters the smut machine or cylinder, (marked Z,) as seen at Figs. l and 2, and a large amount of the smut-balls, cheat, and other filthy substances are drawn over the arch F by t-he current of atmosphere -created by'the fan to the point marked J, where another separation takes place, the smut-balls and dust passing into the fan-box D immediately opposite the point marked J through an opening,

(marked 0,) as represented by black lines drawn over the diagram, which represents the materials of the machine, (marked A.) At this point the defective grains of wheat and cheat that are heavier than the smut-balls and other substance that may have been drawn over fall out at the valve J in a'clean state to be ground as horse-food. This is the lirst and most important operation of cleansing the wheat, as

vention, and never enter the smut-machine to be broken into a black dust with thewheat as it passes through the rubbing process to create a darkness upon the surface of the wheatgrains. This, therefore, is quite import-ant to prevent a darkness in the iiour, which originates from the smut-balls and dark substances being broken too largely in all other smutmachines with the wheat. By this process the greater portion vis carried off without en-V tering the smut-machine. The wheat, together with all the impure articles that may not have been carried out by this first operation, falls into the hopper V, as before described, and enters the smut machine or cylinders near the t-he axes ofthe machine upon the horizontal wheel NV, upon which is set or fixed many vertical pins from two to six inches long, through which the wheat in this state is thrown by the centrifugal force as it revolves, striking 'against these pins and breaking to pieces the smut-balls and all other impure articles that may have been left by the first operation, or nearly so,into dust, and this striking against the side of the internal cylinder-case, which is perforated immediately opposite with holes,- as seen in Fig. 2, (marked 2,) through which the dust so made passes into the' chamber betweenthe external and internal cylinder-cases, as seen inFigs. land 2, (marked e,) from whence the dust is eradicated by the fan through the spout marked y, Figs. l and 2, into the fanboX D, and blown out at the spout marked Q, as seen on Fig. 2, back View of the machine. The wheat neXt falls into a circular hopper attached to the internal cylinder-case, as represented by thelines marked l), and extending under the wheel W, with the mouth or opening around the main axis at x. lThe wheat and all articles of lth that may not have been carried off by this operation fall through upon the wheel X, which is constructed in the same manner as the wheel WV, and undergoes the same operation as before by the revolution of this wheel also, which breaks to pieces the smut-balls and other impure articles that may not have been destroyed by the last operation to a still greater extent as it passes through the pins upon this wheel by the centrifugal force to the extremity, at which point the wheat in this state, with all articles of filth-such as rat-dung and mice-dung---too` hard lto have been broken as it passed through the pills upon the wheel X, falls out upon an adjustable reeded rubber, (marked 0,) which sits at the base of the internal cylinder-case, and so constructed that it can be raisedl or lowered by set screws. The wheat in this state is passed between this and another rubber connected to the wheel X, forming a iange all round the bottom like a dished hoop, as seen at i', coming nearthe adjustable rubber, and by the powerful revolution' of this flange-rubber `against the reededrubber every article of filthy substance is broken into dust and thrown round to the spout I with the wheat, and enters the archE at the point marked K. At the point K in the archE a iinal cleansing operation takes place, the whe-at falling out at the' spout of the arch, below the point K, as lseen at @,and the dust,pfaulty grains of wheat, and cheat carried over `the arch E to thepoint marked J by the power of atmospheric suction created by the fan, as before stated, in the arch F, where a last separation takes place, the dust passing into the fan-box D, and, as in the first operation, it is blown out at the spout Q, (seen on Fig. 2,) while all faulty grains of wheat and cheat that may` have come to this point fall out through the valve marked J, as before shown and described of the arch F.

The adjustable reeded rubber is best represented by Fig. 7, in connection with Fig. l, at the lines marked o and w. The line marked o is the'reeded rubber', represented to sit at the base ofthe internal cylinder-case,l as seen in Fig. 7, and may be raised or lowered by setscrews under theframe, above the fan-box, as seen at r, Figs. l and 2, which givesthe name adjustable This reeded rubber can be raised at pleasure to any space for the wheat to pass between that and the ilange-rubber, as the case may require, for complete destruction of all impure articles of filth to which wheat is subject by long standing in mills and other places-of deposit by rats and other animals.

What we claim as our improvement inl this invention is l. The additional air tube or arch F, in connection with the air tube or arch E, for the purpose of receiving the wheat through an aperture in pipe F, above the hopper V, and from the hopper G, as described.

2. The adjustable reeded rubber o; combin ed with the iiange-rubber i, constructed and operating as and for the purposes de# scribed. j
